This is an online set of information about astronomical alignments of ancient structures and buildings. Learners will read background information about the alignments to the Sun in such structures as the Great Pyramid, Chichen Itza, and others....(View More) Next, the site contains 10 short problem sets that involve a variety of math skills, including determining the scale of a photo, measuring and drawing angles, plotting data on a graph, and creating an equation to match a set of data. Each set of problems is contained on one page and all of the sets utilize real-world problems relating to astronomical alignments of ancient structures. Each problem set is flexible and can be used on its own, together with other sets, or together with related lessons and materials selected by the educator. This was originally included as a folder insert for the 2010 Sun-Earth Day.(View Less)

In this laboratory activity, learners explore the difference between heat and temperature, and explore the rate of heat transfer from one substance to another as it depends on the density of the substances being investigated. The activity can be...(View More) conducted either in a science lab or in a kitchen. It is one of two activities supporting the scientific investigation of the Interstellar Medium (ISM), and is linked to reading material, reading review questions and problems, a teacher answer sheet, and glossary.(View Less)

In this activity, students measure the length of the day using the rotation of the Earth, and discover that the Sun is not exactly in the same place at the same clock time every day, understand that the changes are due to motions of the Earth, and...(View More) lead to differences in solar, star, and sidereal time. This resource is from PUMAS - Practical Uses of Math and Science - a collection of brief examples created by scientists and engineers showing how math and science topics taught in K-12 classes have real world applications.(View Less)

This is an activity about the Sun's position in the sky. Learners will use a clear plastic hemisphere to create a model of the sky and mark the position of the Sun in the sky on the hemisphere several times throughout the day. From this information,...(View More) learners can determine the location of sunrise, sunset, and the Sun's height at noon. This activity can be repeated over the course of several days, weeks, and/or months.(View Less)
